categorical feature(类别变量)是在数据分析中十分常见的特征变量,但是在进行建模时,python不能像R那样去直接处理非数值型的变量,因此我们往往需要对这些类别变量进行一系列转换,如哑变量或是独热编码。 在…

You only have to specify the encoding when the first argument you pass to the methods is a string. If you call thebytearray()method with an integer or an iterable of integers, you don't have to specify the encoding. main.py print(bytearray(5))# 👉️ bytearray(b'\x00\x00\x00\x...
